Written to give students and professionals the basics required to implement network functionality in the Linux kernel, this book also addresses everyone who wants to deepen their understanding of network specific processes in an operating system. This book introduces the key components and mechanisms of the Linux kernel and the designs of communication systems.

This unique Linux networking tutorial/reference by experts provides readers with a practical overview and understanding of the implementation of networking protocols in the Linux kernel. The book shows how networking behavior and protocols can be implemented within the Linux operating system. The book provides an introduction to the Linux kernel, mainly focusing on the upcoming kernel version 2.4 but also valid for version 2.2 kernels.

The organization of the book follows the TCP/IP layering model, beginning with the kernel's network device drivers, continuing with link-layer protocols such as PPP, and finally giving a description of all core protocols of the TCP/IP protocol family.
